+# Environment Configuration Implementation Guidelines for .NET SDK
+
+## Golden Rule
+When unsure about implementation details, ALWAYS ask the developer.
+
+## Implementation Status
+**IMPORTANT**: The .NET SDK environment configuration feature is **NEARLY COMPLETE** and functional. Focus on bug fixes and test improvements rather than reimplementation.
+
+## Required Implementation Plans
+All work on environment configuration MUST follow these plans:
+- **Primary**: `@general-implementation-plan.md` - Overall architecture and cross-SDK consistency
+- **Secondary**: `@dotnet-implementation-plan.md` - .NET-specific implementation details
+
+## Current Implementation Analysis
+
+### ✅ COMPLETED Components
+1. **C Bridge Layer** (`src/Temporalio/Bridge/sdk-core/core-c-bridge/src/envconfig.rs`)
+   - `temporal_core_client_config_load` - Loads all profiles
+   - `temporal_core_client_config_profile_load` - Loads single profile
+   - Proper memory management and error handling
+   - JSON serialization between Rust and C
+
+2. **P/Invoke Bridge** (`src/Temporalio/Bridge/EnvConfig.cs`)
+   - Complete async/await implementation
+   - Proper callback handling and memory cleanup
+   - JSON deserialization to .NET objects
+
+3. **API Surface** (`src/Temporalio/Client/Configuration/`)
+   - `ClientConfig` - Main configuration container
+   - `ClientConfigProfile` - Profile-specific settings  
+   - `ClientConfigTls` - TLS configuration
+   - `DataSource` - Flexible data source abstraction
+   - Integration with `TemporalClientConnectOptions`
+
+## Implementation Plans
+All work on environment configuration MUST follow these detailed plans:
+- **Primary**: `@general-implementation-plan.md` - Overall architecture and cross-SDK consistency
+- **Secondary**: `@dotnet-implementation-plan.md` - .NET-specific implementation details and current status
+- **Assessment**: `@envconfig-assessment.md` - Comprehensive cross-SDK analysis and comparison
+
+## Current Status Summary
+The .NET SDK implementation is **NEARLY COMPLETE** and functional, requiring only:
+1. **Critical bug fix** for TLS field name mismatch (see dotnet-implementation-plan.md)
+2. **Comprehensive test coverage** following Python/TypeScript patterns
+3. **Validation** of bridge layer functionality
+
+See `@dotnet-implementation-plan.md` for detailed status, issues, and completion steps.
